Three electric charges are placed along the x-axis as follows :  a +16 nC charge is placed at x = -8 cm,  a -20 nC charge is placed at x = +4 cm, and a -10 nC charge is placed at x = +10 cm. Therefore, the magnitude of the electric field at the origin is (k is the Coulomb's constant) Group of answer choices k (11.10 x 10-5 ) N/C k (1.1 x 10-5 ) N/C k ( 1.6 x 10-5 ) N/C

Three positive charges are arranged as shown at the corners of a rectangle. 2.26 nC 0.208 m 1.13 nC 2.22 nC 0.624 m Find the magnitude of the electric field at the fourth corner of the rectangle. The value of the Coulomb constant is 8.98755 x 10° N · m²/C². Answer in units of N/C. What is the direction of this electric field (as an angle measured from the positive r- axis, within limits of -180° to 180°, with counterclockwise positive)? Answer in units of °
